A federal judge on Monday rejected an 11th-hour bid by Nevada rancher Cliven Bundy to dismiss criminal charges he faced for a 2014 armed standoff against federal agents, finding no basis for defense claims that prosecutors concealed evidence. The ruling by U.S. District Judge Gloria Navarro paved the way for the trial of Bundy, 71, and his three co-defendants, including sons Ammon and Ryan Bundy, to proceed with opening statements on Tuesday in a trial expected to last through February.
